UKL1J470MPD

The UKL1J470MPD is a miniature aluminum electrolytic capacitor in Nichicon’s UKL low-leakage series. It is a radial-lead, polarized capacitor rated at 47 µF and 63 V, designed for compact board-level implementations where low leakage and low dissipation are required.

This part serves applications in audio circuits and other electronic designs that benefit from a compact φ10 × 12.5 mm can, low tanδ, measurable ripple-handling capability, and an operating temperature range of –40 °C to 85 °C.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable for polarized DC applications requiring moderate capacitance at mid-range voltage.
• Low Leakage Current: Specified leakage current of 5.922 µA, supporting low-bleed designs and maintaining DC bias stability over time.
• Low Dissipation Factor (tanδ): tanδ of 0.07 measured at 20 °C, 120 Hz, indicating reduced AC loss and improved efficiency in filtering and coupling roles.
• Ripple Current Capability: Low-frequency ripple current rating of 200 mA (120 Hz) and high-frequency rating of 400 mA (10 kHz), enabling effective smoothing of power rails and handling of audio-frequency ripple components.
• Compact Radial Package: φ10 × 12.5 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), making it suitable for tight PCB layouts and through-hole assembly.
• Endurance & Temperature Range: Rated for 2000 hours at 85 °C and an operating range of –40 °C to 85 °C, offering predictable life characteristics for designs with these thermal profiles.
• RoHS Compliant: Conforms to RoHS requirements, supporting regulatory compliance for lead-free assemblies.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to match procurement and assembly preferences.

Typical Applications

• Audio circuits — Used for power-supply smoothing, coupling and decoupling in audio devices where 47 µF at 63 V with low leakage and low tanδ supports stable performance.

Unique Advantages

• Low DC leakage: The specified 5.922 µA leakage current reduces bias drift and minimizes standby losses in sensitive circuits.
• Efficient AC performance: A tanδ of 0.07 at 120 Hz indicates low dielectric loss, improving filtering efficiency in audio and power applications.
• Compact form factor: φ10 × 12.5 mm radial can and 5 mm lead spacing provide a small footprint for space-constrained board designs.
• Frequency-aware ripple handling: Rated ripple currents for both low (200 mA at 120 Hz) and high (400 mA at 10 kHz) frequencies ensure usefulness across a range of ripple spectrum conditions.
• Predictable lifetime: 2000 h endurance at 85 °C gives a clear basis for thermal-life planning in products operating within that temperature range.
• Regulatory readiness: RoHS compliance eases integration into lead-free manufacturing processes.
